What is the metal tab on brake pads?
A metal tab fastened to the pad assembly indicates when pads have thinned. As pads wear, the tab rubs against the rotor, causing squealing when the brakes are applied. If you hear screeching, squealing, grumbling or grinding when braking, take your car to a reliable auto shop.
What types of brake pad wear indicators are there?
There are different types of wear indicators for brake pads:
- Ocular inspection: A cut is made in the pad material to the depth where it shall be replaced.
- Mechanical: A metal plate is designed to contact the brake disk causing a noise when the pad has worn down to the desired level.
Do all brake pads have a wear indicator?
The most obvious indicator that your vehicle’s brakes need attention is an incredibly high pitched squeal when you come to a stop. Brake pad manufacturers include a little piece of metal called an indicator on the pad itself. Additionally, many aftermarket and low-cost pads don’t come with a wear indicator at all.
Is there metal in brake pads?
Metallic brake pads are comprised of anywhere between 30% and 70% metals including copper, iron, steel, or other composite alloys. These various metals are combined with graphite lubricant as well as other fillers to complete the brake bad.
Where does the metal tab on brake pads go?
The warning tab is supposed to touch the rotor only when you’re braking. I always put them on the inside against the piston. If the caliper gets sticky the inner pad will wear faster, and usually always does (slightly) anyhow.
What brake pad goes on the inside?
The L pads go on the left side of the calipers (outside pad on the drivers side, inside pad on the passenger side) and the R pads go on the right side (inside of the drivers caliper, outside of the passenger one).
How do you read a brake pad wear indicator?
You might need a flashlight to get a good look at the brake pad. If the pads look thin, less than 1/4″, it might be time to get them replaced. On some brake pads, you might see a wear indicator slot down the center of the pad. If the slot is gone or just barely visible, it’s time for new brake pads.
Can you remove brake wear indicator?
When the pads are worn out the wear indicators just rub against the rotor, no big deal: it’s still the brake pads doing the dirty work in silence. Good thing that you don’t recommend removal of the wear indicators but I cannot see how your situation may be different from others.
Which type of brake pad is best?
CHOOSING THE CORRECT BRAKE PAD If you have a high-performance sport car, or at least drive your vehicle like it is one, you’re likely best off choosing semi-metallic brake pads. On the other hand, if you do a lot of urban commuting, you might find a solid ceramic brake pad to be the better option.
Are ceramic brake pads better than metallic?
Ceramic brake pads typically last longer than semi-metallic brake pads, and through their lifespan, provide better noise control and less wear-and-tear to rotors, without sacrificing braking performance.
Do brake pad squealers go on top or bottom?
What side does the squealer go on brake pads? The squealer should always point toward the disc. That way they work is, as the pad wears, the squealer gets closer and closer to the disc.

What does the wear indicator on the brake pads mean?
The wear indicator is a small metal tab fastened to the brake pad. When the brake pads are worn down and need replacing, this metal tab starts to drag along the rotor, warning the driver of the potential problem. How to Fix It
When do brake pads start to wear out?
Since the brake pads get used whenever you step on the brake pedal, they tend to wear out after about 50,000 miles. However, you can get a longer life out of your brake pads if you use ones which have the right thickness. We will go over thickness levels below.
What happens when your brake pads get too thin?
When your brake pads rub up against the discs, it wears down their friction material. When we measure the thickness of a brake pad, we are measuring the thickness of this material. If your friction material were to get too thin, then it would not be able to slow down your vehicle quickly after you step on the brake pedal.
